From end-of-life magnets to refined rare-earth materials
Building a circular ecosystem
Permanent magnets are essential to electric motors, wind turbines, hard disk drives, consumer electronics and industrial automation. At end of life, they can become a valuable secondary source of critical rare-earth materials.
MiniMines is building an indigenous recovery and refining ecosystem for end-of-life permanent magnets, recovering valuable rare-earth materials and preparing them for re-entry into the manufacturing value chain.
creating a secondary resource stream
Permanent magnets sit inside many of the technologies driving electrification and automation. Rare-earth NdFeB magnets are especially important because they deliver high magnetic performance in compact applications. A strong feedstock strategy is central to a scalable magnet recycling ecosystem. MiniMines can work with partners to evaluate suitable material streams for recovery.
THE CHALLENGE
The challenge is not simply collecting old magnets. It is recovering, separating and refining the valuable materials they contain to a form that can support downstream manufacturing.
MiniMines is developing a circular recovery pathway for permanent magnets that connects feedstock recovery with material refinement. The objective is to move beyond waste handling towards high-value resource recovery and supply-chain re-entry. Our approach brings together controlled feedstock preparation, recovery and refining to produce defined rare-earth chemical products for potential downstream applications.
Rare-earth materials for the next generation
These products represent important intermediate forms in the rare-earth value chain.
The transition to electric mobility and renewable energy will require unprecedented volumes of rare-earth materials. Meeting this demand sustainably requires a shift from a linear economy to a circular one, like MiniMines.
End-of-life permanent magnets, magnet-containing components and suitable industrial scrap are identified and sourced.
Feedstock is assessed for composition, contamination and suitability for the recovery route.
Magnets and magnet-containing components undergo appropriate preparation to create a controlled feedstock
Rare-earth-bearing material is processed through the relevant recovery pathway
Recovered rare-earth streams are refined into defined chemical products.
Responsible EXTRACTION, Big Impact
Rare-earth permanent magnets are closely tied to electric mobility, renewable energy and high-performance motors. As these applications grow, so does the strategic value of recovering rare-earth materials already in circulation.

MiniMines' wider clean-tech platform is built around proprietary extraction and recycling processes.
Designed to work with businesses and end users on practical resource-recovery opportunities.
Treating end-of-life materials as resources rather than waste.
Permanent magnet recycling is the recovery and processing of materials from end-of-life permanent magnets so valuable magnetic and rare-earth materials can be reused or refined for further applications.
Yes. Rare-earth permanent magnets, including NdFeB magnets, can be processed through recycling routes that recover valuable rare-earth elements such as neodymium, praseodymium and dysprosium.
NdFeB permanent magnets contain mainly neodymium and praseodymium, with dysprosium present in some formulations. The recoverable elements depend on the magnet chemistry and feedstock.
NdFeB magnet recycling is the recovery of valuable materials from neodymium-iron-boron permanent magnets found in products such as EV motors, wind generators, hard disk drives and industrial equipment
MiniMines’ permanent magnet recycling initiative is focused on Nd-Pr Sulphate, Nd-Pr Hydroxide, Nd-Pr Oxide and Dy Chloride.
Recycling can create secondary sources of critical rare-earth materials, reduce material loss and support more resilient circular supply chains.
Permanent magnets are used in electric and hybrid vehicle motors, wind turbine generators, industrial motors, automation systems, hard disk drives and consumer electronics.
Businesses with suitable end-of-life permanent magnets, magnet-containing components or relevant industrial scrap can contact MiniMines to discuss feedstock suitability and recovery opportunities.
